18TH/19TH CENTURY

Zhai jie is the ceremonial requirement for abstinence before one worshipped their ancestors, the Heavens or other deities, which usually lasted for three days. During this time, one should refrain from eating meat and fragrant herbs such as onions, chives, garlic and the like, consuming alcohol, and from any intimate acts.
Abstinence plaques were made in various materials, including jade, bamboo, painted enamel and porcelain.
